Chinese researchers tried to sell UK health data
Chinese researchers tried to sell UK health data
Introduction
Three people from Chinese hospitals tried to sell health data of about 500,000 people on Alibaba. This stopped data access and started questions about safety.
Main Body
The researchers had permission to use the data from UK Biobank. They put listings on Alibaba with information like age, gender, and lifestyle. They did not include names or addresses. Someone told UK Biobank about the listings. UK Biobank stopped the researchers' access. No one bought the data. UK Biobank stopped all data access to stop more problems. The boss said sorry to the volunteers. A minister called the sale a bad thing. Some politicians asked for an investigation. This is not the first problem with Chinese researchers. In 2023, people worried about Chinese scientists getting doctor records. In 2024, a check said the data sharing was safe. In 2025, the health secretary allowed more data to go to UK Biobank. A former spy chief said this was a bad decision. MI5 warned about Chinese interference in science. A politician said the government gave a 'gift to China' and people do not trust the system anymore. A professor said this was the 198th time data came out. He said people do not remove stolen data from the internet enough.
Conclusion
UK Biobank stopped data access to fix safety problems. The sale attempt made politicians want an investigation. People worry about the safety of health data in international research.

Attempted Sale of UK Biobank Data by Chinese Researchers Prompts Security Review and Political Scrutiny
Introduction
Three individuals from separate Chinese research hospitals tried to sell de-identified medical records of about 500,000 UK Biobank participants on the e-commerce platform Alibaba. This incident caused a suspension of global data access and renewed debate about whether security rules for international research partnerships are strong enough.
Main Body
The attempted sale involved listings posted by researchers who had originally gained legitimate access to the UK Biobank database, which contains de-identified health data from NHS volunteers. The listings included fields such as gender, age, month and year of birth, assessment centre data, attendance records, socioeconomic status, and lifestyle habits. However, they did not include names, addresses, or contact details. UK Biobank, a registered charity, reported that it was alerted to the listings by an anonymous whistleblower and then revoked access for the three institutions, although it refused to name them. The listings were removed before any sale took place. As a result, UK Biobank paused global access to its database to prevent further unauthorized downloads and resale. Professor Sir Rory Collins, the charity’s chief executive, apologized to participants for the concern this incident caused. Technology Minister Ian Murray described the leak as an “unacceptable abuse,” and several parliamentarians, including former Conservative leader Sir Iain Duncan Smith and shadow national security minister Alicia Kearns, called for a formal inquiry. This event happened against a background of previous controversy over Chinese researchers’ access to UK Biobank data. In 2023, plans to allow Chinese scientists to access general practitioner records of 503,000 volunteers faced objections from MPs, security experts, and former intelligence chiefs. They warned that the data could be used for bioweapons development or to help China’s biotechnology industry. In April 2024, NHS England audited UK Biobank’s international data-sharing processes, including its review of applications from China, and the audit was passed. Later, in February 2025, Health Secretary Wes Streeting authorized the transfer of coded GP data from all volunteers to UK Biobank. Former MI6 chief Sir Richard Dearlove compared this decision to the cancelled plan to allow Huawei involvement in the UK’s 5G network. MI5 Director General Sir Ken McCallum had previously warned against Chinese interference in science and technology and urged institutions to evaluate risks in partnerships. Alicia Kearns argued that the government had given a “gift to China” and that public trust had been damaged. She demanded clarification on which institutions had their access revoked, which had links to the Chinese state, and who authorized the override of MI5 warnings. Professor Luc Rocher of the Oxford Internet Institute pointed out that this was the 198th known exposure of UK Biobank data since the previous summer. He added that not enough was being done to remove stolen data from the internet, with some data still available for download.
Conclusion
UK Biobank has temporarily stopped global data access while it works to fix security weaknesses. The attempted sale has increased political demands for an investigation into the decision-making process that allowed Chinese researchers to access the database. It has also highlighted ongoing concerns about protecting sensitive health information in international research collaborations.

Attempted Sale of UK Biobank Data by Chinese Researchers Prompts Security Review and Political Scrutiny
Introduction
Three individuals affiliated with separate Chinese research hospitals attempted to sell de-identified medical records of approximately 500,000 UK Biobank participants via the e-commerce platform Alibaba. The incident has prompted a suspension of global data access and renewed debate over the adequacy of security protocols governing international research collaborations.
Main Body
The attempted sale involved listings posted by researchers who had initially obtained legitimate access to the UK Biobank database, a repository of de-identified health data from NHS volunteers. The listings included fields such as gender, age, month and year of birth, assessment centre data, attendance records, socioeconomic status, and lifestyle habits, but did not contain names, addresses, or contact details. UK Biobank, a registered charity, stated that it was alerted to the listings by an anonymous whistleblower and subsequently revoked access for the three institutions, though it declined to name them. The listings were removed before any transactions occurred. In response, UK Biobank paused global access to its database to prevent further unauthorized downloads and resale. Professor Sir Rory Collins, the charity’s chief executive, issued an apology to participants for the concern generated by the incident. Technology Minister Ian Murray characterized the leak as an “unacceptable abuse” and calls for a formal inquiry were made by several parliamentarians, including former Conservative leader Sir Iain Duncan Smith and shadow national security minister Alicia Kearns. The event occurs against a backdrop of prior controversy over Chinese researchers’ access to UK Biobank data. In 2023, plans to grant Chinese scientists access to general practitioner records of 503,000 volunteers drew objections from MPs, security experts, and former intelligence chiefs, who warned that the data could be exploited for bioweapons development or to advance China’s biotechnology sector. In April 2024, NHS England audited UK Biobank’s international data-sharing processes, including its assessment of applications from China, and the audit was passed. Subsequently, in February 2025, Health Secretary Wes Streeting authorized the transfer of coded GP data from all volunteers to UK Biobank. Former MI6 chief Sir Richard Dearlove compared this decision to the aborted plan to allow Huawei involvement in the UK’s 5G network. MI5 Director General Sir Ken McCallum had previously cautioned against Chinese interference in science and technology and urged institutions to evaluate risks in partnerships. Alicia Kearns asserted that the government had provided a “gift to China” and that public trust had been damaged. She demanded clarification on which institutions had their access revoked, which had links to the Chinese state, and who authorized the override of MI5 warnings. Professor Luc Rocher of the Oxford Internet Institute noted that this was the 198th known exposure of UK Biobank data since the previous summer and that insufficient measures were being taken to remove stolen data from the internet, with some data remaining available for download.
Conclusion
UK Biobank has temporarily halted global data access while it addresses security vulnerabilities. The attempted sale has intensified political demands for an investigation into the decision-making process that permitted Chinese researchers to access the database, and has highlighted ongoing concerns about the protection of sensitive health information in international research collaborations.
